The details under the hood matter just as much as the ones on the outside. This Custom Billet Radiator & Intercooler Cap is a precision CNC-machined upgrade built on a genuine Motorcraft EC743 OEM cap — delivering factory-level reliability with the kind of engine bay presence that sets a build apart.

Machined from 6061 billet aluminum and finished in a durable satin black powder coat, the cap is engineered to withstand the heat, chemicals, and demands of daily driving and performance builds alike. Each cap is then fiber laser engraved with crisp, permanent detail that adds depth and contrast right where everyone looks first.

The billet cover is professionally press-fitted onto an authentic Motorcraft EC743 clicker-style cap, ensuring proper alignment, sealing, and OEM-level functionality across 3,000+ Ford, Lincoln, and Mercury platform applications. It's a small detail that makes a big statement. Suitable for Radiator and/or intercooler reservoir.

Choose from four standard engraving designs or submit your own for a completely custom piece.

Standard Design Options:

  • Driven Build Co. logo

  • Coyote

  • Cobra

  • Blank
